Krystol Waterstop Grout is a primary component of the Krystol Waterstop System and is used to permanently waterproof concrete construction joints. In addition to Kryton’s proven Krystol technology, Krystol Waterstop Grout contains fiber reinforcements which improve crack resistance and durability. These active ingredients combine chemically with water and concrete to form millions of needle-shaped crystals that grow in all di rections to fill any capillary pores, cracks and joints that might otherwise allow water to pass. Krystol Waterstop Grout is used in conjunction with Krystol Waterstop Treatment to form the complete system.
